description	Ingest a LeRobot (HuggingFace) dataset into Rerun. Read when converting a LeRobot dataset to RRDs, splitting it into per-episode segments, or registering it on a Rerun catalog. Covers the built-in directory importer (log_file_from_path), the RrdReader + send_chunks per-episode split, and when to drop to ParquetReader for custom control.

Rerun LeRobot ingestion

Rerun has a built-in LeRobot importer: point log_file_from_path (or the viewer, or rerun <dir> on the CLI) at the dataset directory and it ingests episodes, camera videos, and state/action tables with no conversion code. There is no chunk-level LeRobotReader; the chunk-processing route is to import first, then reprocess the resulting RRD with RrdReader.

The download step needs huggingface_hub.

Step 1: dataset -> one combined RRD

from huggingface_hub import snapshot_download
import rerun as rr

dataset_dir = snapshot_download(repo_id="rerun/so101-pick-and-place", repo_type="dataset", local_dir=dest)

with rr.RecordingStream()  rec:
    rec.save((combined_rrd))
    rec.log_file_from_path((dataset_dir))
